Reading this description may make you cringe at the thought of what kind of combo could possibly accomplish the task, however this trophy is actually rather simple. Go in to a local versus match and hover over Hazama. Press L1 to enable beginner mode, then select him against whomever. Fill your heat meter to 100 by either attacking the opponent, letting them hit you or even doing instant blocks.
We're now going to do Hazama's Astral Heat. In order to do this, it must be the winning round for you and the opponent must have less than 25% health. You'll know when you can do it when your avatar beside the health bar begins to flash. Now, hold Square, Triangle and Circle while standing close to your opponent. The heat should initiate if you've fulfilled the criteria and you'll have your trophy while it's being executed.
